I got my little brother at the mechanic shop with my teg.
And they said the car needs a vibration damper.
What is that ?

 

There are different types of dampeners, but the one I think he is referring to is a engine vibration dampener located in the steel frame of the front bumper..
it is cylindrical in shape and has rubber bumpers attached to each end , its about the same size the cardboard tube that is located in the center of rolls of paper towels, weighs about 5 lbs and made of solid steel.. Its purpose is to dampen the vibration and sound that can travel through a steel frame..
